Someone already brought up selling the single genes and such... But are you aware of the issues with spider gene as well? It's not just selling potential, it's health potential as well.
My breeding female is a killer queenbee [Super pastel lesser spider]. Any time you are working with spider, you must be aware that you may not be able to sell the offspring as well. I bred my girl because her spider gene impact is MINIMAL. She only wobbled the first week I got her as a yearling due to stress.
Out of her 4 hatchlings, 3 have the spider gene. All 3 are BEL, so it isn't something you can readily see on them, but all 3 will occasionally wobble while cruising their habitats. One of them, I'm still going to rehome, but as pet quality only because he also has the spider head tilt. None of mine have issues eating.... but there still is the very rare chance you will hatch a spider who's wobble is so severe that you may need to consider culling it if it cannot eat. You also run the risk of dead hatchlings if you breed a spider to spider or champagne. It's a fatal super gene
I will admit, GHI mojaves are beautiful and that is one of the snakes I was thinking of working towards. I understand the appeal. If you are seriously considering breeding you will definitely need to plan what you are breeding for and how to get there. Having a powerhouse male is ideal way to start. By this I mean a male who is already a super or allelic combo. I got a great price on my female, so I started a bit backwards. But the male I bred her to is a crystal enchi pastel. Every offspring from that pair is at the very least either pastel mojave or pastel special. I lucked out and all 4 hatchlings from my first clutch were white snakes. I was crossing fingers for a Blue Eye Lucy or two... But I wanted a female BEL holdback and they were all males. lol. So be careful what you wish for as well.
Either way, owning and breeding can be a rewarding experience. But make sure to do your research on what care you'll need or what kind of genetic combos can do what you're looking to do.
